Abstract: A method for producing carbon nanotubes and/or fibers, such as carbon nanotubes, involves sparging a gas (such as carbon dioxide) through a liquid hydrocarbon (such as crude oil) in the presence of an effective amount of metal oxide particles (such as MgO, Al2O3, CeO2, and/or SiO2 nanoparticles having a size in the range from about 2 nm to about 10 microns, and which may have a bimodal particle size distribution) at a temperature in a range of between about 70 to about 350° C. to produce carbon nanotubes and fibers having a size range of from about 50 nm to about 20 microns.
